Abstract :
This paper presents a new multi-phase stator cage winding suitable for different synchronous and asynchronous machine types. The new winding construction is characterized with high quality MMF distribution, simple construction, and extremely short end winding length. The stator consists of a stack of iron lamination, but with massive conductors in each slot, being short-circuited at one axial end, and with each slot conductor supplied separately at the second end of the machine. To show the capability and the efficiency of the new machine concept, an asynchronous motor (ASM) for traction application in electric vehicles (EV) is designed and investigated. The simulation results show high power density, high efficiency, and thermally robust for the new ASM design.
